IMPROVEMENT IN EED-BQTTOMS.

Specification forming part of Letters Patent No. 133,090, dated November19, 1872.

To all whom it may concern:

Be it known that we, DAVID FRANKFODER and GEORGE W. MoGEoRGE, ofWakarusa, in the county of Elkhart and State of Indiana, have invented anew and useful Improvement in Spring Bed-Bottoms; and we do declare thatthe following is a true and accurate description thereof, referencebeing had to the accompanying drawing and to the letters of referencemarked thereon and being a part of this specification, in which- Figure1 is a perspective view of our improvement with the bolster raised, andFig. 2 is a detached perspective view of one of the springs.

' Like letters refer to like parts in each figure.

The nature of this invention relates to an improvement in theconstruction of spring bedbottoms, and to an adjustable bolster to beused in connection therewith. The object of the invention is to renderthe bed-bottom more elastic from the middle to the head, where moreelasticity is needed than elsewhere, and also to raise the head of theoccupant more or less above the horizontal plane, and for invalids toelevate the bolster to a sitting position. The invention consists in thegeneral construction and arrangement of the several parts, as more fullyhereinafter set forth.-

In the drawing, A represents the rectangular frame of our bed-bottom, inthe head and the slats G, by means of C-springs c, to support the lowerextremity of the mattress. A

little nearer the head, from the center of each side rail of the frame,we insert in the latter a spring, B like those first described, withtheir bales pointing inwardly to receive acrossbar, 0 which passes underand supports the longitudinal slats. By employing this crossbar a lessernumber of longitudinal slats are required, and they are supported at thepoint where the superimposed weight is greatest. D is a bolster-frame,formed of wooden bars mortised together to make three sides of arectangle, the ends of which are pivoted or hinged to the main frame ate. A smaller and lighter frame, d, is pivoted to the side bars of thebolster-frame, for which it forms a prop, the ends of the cross-barengaging with ratchet-notches f cut in the edges of the side bars of themain frame, so that the bolster-frame may rest horizontally on the mainframe or be supported between the horizontal and vertical planes at anydesired angle.- The end bar of the bolster-frame is provided withsprings B of the same style as the others, through the eyes of whichproject short slats 0 whose ends are connected by a cross-slat, O. Thelower ends of the slats Q are secured to the cross-bar 0 between themain slats, which cross-bar is free to rotate in its supports with themovement of the bolster, which may be elevated to any desired position,and, when in the horizontal position, its slats, in connection with themain slats, give the upper half of the bed a better support, and a moreelastic one than can otherwise be had.

What we claim as our invention, and desire to secure by Letters Patent,is

The frame A, springs B, and slats O 0 in combination with the hingedsupporting-frame D, prop-frame d, springs 13, slats (J 0 and cross-bar 0arranged and operating in the manner and for the purpose set forth.
